Why exactly 4 a day and not more
Instagram watches pace. A real agency does not push 20 posts in a row: one or two flats in the morning, another one after lunch. That is why the ceiling in BuzzPost is 4 posts a day per account, and it is a service rule, not a setting you can bypass. Marked 30 listings on Sunday? No problem: they go out over a week, 4 each day, and the account looks alive and steady instead of firing everything on one day and going silent. The rule protects you too: an account with an even pace gets temporary restrictions less often. How the post itself is built is on the Instagram auto-posting page.
